Abstract

本发明所涉及到的洋流发电机组主轴承，将原来普通轴承的内圈加宽，作为夹布油封的接触面。采用新设计的轴承，不需要另外装配独立的密封环，减少了装配工作量和成本。

Description

一种用于洋流发电机组的主轴承
技术领域：
本发明涉及一种用于洋流发电机组的主轴承。
背景技术：
附图1为普通的洋流发电机组主轴承示意图，附图2为普通的洋流发电机组主轴承装配示意图。为了保证轴承座(1)的密封，在轴承座(1)两端需要装配夹布油封(2)。由于主轴(4)的硬度达不到夹布油封(2)要求，因此需要在夹布油封(2)和主轴(4)之间装配密封环(5)，密封环(5)硬度需大于58HRC。
这种设计主要有以下缺点：
由于密封环(5)与主轴(4)是过盈配合，因此装配时需要加热密封环(5)后，才能装入主轴(4)。这样增加了装配工序和装配时间，增加了制造成本。
发明内容：
本发明所涉及到的洋流发电机组主轴承，将原来普通轴承的内圈加宽，作为夹布油封的接触面。采用新设计的轴承，不需要另外装配独立的密封环，减少了装配工作量和成本。
附图说明：
图1是普通的主轴承示意图。
图2是普通主轴承装配示意图。
图3是本发明二维结构剖面图。
图4是本发明装配图。
图2中：1、轴承座；2、夹布油封；3、主轴承；4、主轴；5、密封环。
图4中：1、轴承座；2、夹布油封；3、主轴承；4、主轴。
